MICHAEL TROMLY,OF WASHINGTON, DISTRICT OF COLUMBIA. Letters PatentNo. 84,233, dated November 17,1868.

IMPROVEMBN '1" IN GUN-LCCKS.

To all whom it may canoe/m I Be it known that 1, MICHAEL TROMLY, of the city and county of: Washington, in the District of Columbia, have invented anew and improved Safety-Lock for Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is a side view.

Figure 2 is a side elevation,

Figure 3 is a cross-sectidn through the hammer, taken in the line x x of fig. 2.

The nature of this invention consists in constructing the hammer in two parts, the upper one, containing the head, being so attached to the lower part that it can slide about a half inch upon the latter, and so operating that when the hammer is bent back to a full cock,;-and sprung from that position, centrifugal force throws the head outward, so that it can strike the cap and explode it; but when let down by the thumb, or sprung from less than a half. cook, the head will not be thrown out in the'manner described, but will strike upon a guard near the nipple, and be prevented from coming in contact with the cap. The hammer itselfis so formed as to guard-the cap when In the drawings, A represents the lower part or shank of the haminer, and B the upper part, sliding freely about a half inch in a longitudinal guide-groove on the side of the part A, and held in position by headed pins or screws, 6 e, fixed to the part A, and extending through the part B, in slots s 3, about half an inch in length, the heads .of the pins or screws coming on the outside of the part B. In this way a very firm and substantial connection'is made between the two parts, while the upper or movable part is free to slide up and down upon the shank B, or lower part.

a is the nipple, and G is a metallic guard just behind it, and projecting up nearly to the top of the nipple, at a distance of about an eighth of an inch from it;

The face of the hammer is formed with a recess, m, which comes in contact with the cap,'to explode it,

when centrifugal force throws the part B outward, as

above described, but which, when the hammer is let gently down, or falls from less than a half cock,? strikes and restsvupon the guard Gr. The shoulders i i keep the movable part B in place when thus resting upon thegu'ard, while the projection 0, formed as.

clearly shown in the drawings, extends'over the cap,

and protects it from injury.

as described. v
